How to enable border with rose-pine theme or any theme

[EliezerAmbion]

I am trying to add a border for my auto-completion and hover. I only got to enable the auto-completion border.

my cmp config for setting up the border:

      window = {
        completion = {
          border = 'double',
        },
        documentation = {
          border = 'rounded',
        }
      },
      -- sources for autocompletion
      sources = {
        { name = 'nvim_lsp' }, -- lsp
        { name = 'path' },     -- file system paths
        { name = 'luasnip' },  -- snippets
        { name = 'buffer' },   -- text within current buffer
      },

      mapping = {
        ['<C-k>'] = cmp.mapping.select_prev_item(),
        ['<C-j>'] = cmp.mapping.select_next_item(),
        ['<C-d>'] = cmp.mapping.scroll_docs(-4),
        ['<C-u>'] = cmp.mapping.scroll_docs(4),
        ["<C-e>"] = cmp.mapping.abort(),
        ['<CR>'] = cmp.mapping.confirm { select = true },
      },

      formatting = {
        format = lspkind.cmp_format({
          maxwidth = 60,
          ellipsis_char = "...",
        }),
      },
    }

I also can't find how to enable the hover border.
Does anyone know how to do this?
